Near Core Magnetic Field Strength Bounds

Considering the vast importance of magnetic fields on the study of stellar structure, the near core magnetic field strength of stars is still a challenge to observe and calculate. Convective core main sequence stars that are lacking in observed low-frequency g modes can serve as a means to calculate magnetic field strengths. Using methodology from a previous study of near core magnetic fields of main sequence stars and a data set of 37 stars, we use asteroseismology to place these upper bounds on the magnetic field strength and better understand the internal stellar structure of these observed stars. We find that in these 37 stars, the upper limit for the magnetic field strength is of the order 10 KG, proving to be consistent with previous findings from Duguid et al. (2024). We put forth these findings to provide better information to compare stellar magnetic fields to other stellar properties across stars on the main sequence.
